其中一个没有获取到对应值就调用后台页面其他ajax访问。

case 'insert_message_phone':
      $message_id = $_REQUEST['message_number'];
      $message_gather = $_REQUEST['message_gather'];
      $sql = "insert into s_message_config (message_id,phone_gather) values ('$message_id','$message_gather')";
      $obj_db_main->doexec($sql);
      if(mysqli_affected_rows($obj_db_main->dbconn)>0){
         $Jsonstr['rltcode']=1;
         $Jsonstr['description']="插入成功";
         echo json_encode($Jsonstr);
/*       header("location:message_config.php");*/
         exit;
      } else {
         $Jsonstr['rltcode']=0;
         $Jsonstr['description']="插入失败";
         echo json_encode($Jsonstr);
         exit;
      }
      break;
   case 'send_message':
      $id = $_REQUEST['id'];
      $sql = "select phone_gather from s_message_config where id = $id";
      $result = $obj_db_main->doquery_row($sql);
      $message_str = $result['phone_gather'];
      $message_phone = explode(',',$message_str);
      $Jsostr['phone'] = $message_phone;

而且输出值不仅仅输出当前的，还会输出之前定义过的。
